A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.

This method is promoted by a commercially available, moisture-stable, and inexpensive nickel(II) precatalyst.

An efficient sequence based on the Ugi-azide reaction and rhodium(III)-catalyzed intermolecular annulation has been established for the preparation of tetrazole-isoquinolone/pyridone hybrids. Several N-acylaminomethyltetrazoles were reacted with arylacetylenes to form the hybrid products in moderate to very good yields. The method relies on the capacity of the rhodium catalyst to promote C(sp(2))-H activation in the presence of a suitable directing group. The Ugi-azide reaction provides broad molecular diversity and enables the introduction of the tetrazole moiety, which may further assist the catalytic reaction by coordinating the metal center. The scope of the isoquinolones is very wide and may be extended to the preparation of complex compounds having heterocyclic moieties such as pyridone, furan, thiophene and pyrrole, as well as the corresponding benzo-fused derivatives. The developed procedure is simple, reproducible and does not require inert conditions.

Early studies demonstrated that over expression of indoleamine 2,3-dioxygenase (IDO1) in tumor microenvironment results in tumor immune escape. Herein, in order to simplify the structure of two kinds of IDO1 inhibitors from marine alkaloid, Exiguamine A and Tsitsikammamines, we designed, synthesized a series of 1H-indole-4,7-dione derivatives and evaluated their inhibitory activity in IDO1 enzyme and in IFN-gamma stimulated Hela cells in vitro. The structure-activity relationship demonstrated that 5-(pyridin-3-yl)-1H-indole-4,7-dione is a promising scaffold for IDO1 inhibitors and most compounds with this core showed moderate inhibition potency at micromole level. Our further enzyme kinetics experiments reveal that these new developed compounds might act as reversible competitive inhibitors of IDO1.

A stereoselective synthetic approach to the natural product (+)-nivetetracyclate A is reported. The tetracyclic skeleton was assembled in a convergent manner by an alkylation to a diarylmethane and subsequent Friedel-Crafts acylation. Further key steps are an asymmetric Sharpless epoxidation and the boron trifluoride-mediated diastereoselective rearrangement of an epoxy alcohol to a beta-hydroxy aldehyde. Optimized timing for the deprotection step and the chemo- and stereoselective Noyori-transfer hydrogenation of a 1,4-diketone allowed the late stage introduction of the C4 stereocenter.

A metal-free aromatic electrophilic substitution reaction using nitrosoarenes as the electrophile in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. HFIP activates nitrosoarene towards the electrophilic C-H amination followed by a concomitant N-O bond cleavage to deliver diarylamines without requiring any extra reagent or further treatment. The dual electrophilic nature of nitrosoarene permits a switchover of selectivity to C-H oxygenation furnishing dearomatizedp-iminoquinones following a unique mechanistic rationale of two consecutive [2,3] sigmatropic rearrangement in nitroso-chemistry.

Solvent reorganization is a major driving force of protein-ligand association, but the contribution of binding site waters to ligand affinity is poorly understood. We investigated how altered interactions with a water network can influence ligand binding to a receptor. A series of ligands of the A(2A) adenosine receptor, which either interacted with or displaced an ordered binding site water, were studied experimentally and by molecular dynamics simulations. An analog of the endogenous ligand that was unable to hydrogen bond to the ordered water lost affinity and this activity cliff was captured by molecular dynamics simulations. Two compounds designed to displace the ordered water from the binding site were then synthesized and evaluated experimentally, leading to the discovery of an A(2A) agonist with nanomolar activity. Calculation of the thermodynamic profiles resulting from introducing substituents that interacted with or displaced the ordered water showed that the gain of binding affinity was enthalpy driven. Detailed analysis of the energetics and binding site hydration networks revealed that the enthalpy change was governed by contributions that are commonly neglected in structure-based drug optimization. In particular, simulations suggested that displacement of water from a binding site to the bulk solvent can lead to large energy contributions. Our findings provide insights into the molecular driving forces of protein-ligand binding and strategies for rational drug design.

The consecutive addition of acyl radicals and N-alkylindole nucleophiles to styrenes was established, as well as some additional radical-nucleophile combinations. Both aryl and aliphatic aldehydes give reasonable yields. The reaction proceeds best for alpha-substituted styrenes, effectively creating a quaternary all-carbon center. Some iridium-based photoredox systems are catalytically active; furthermore, a base is needed in this transformation. Radicals are formed by reductive perester cleavage and hydrogen atom transfer.

We present an atom-economic strategy to catalytically generate and intercept nitrile anion equivalents using hydrogen transfer catalysis. Addition of alpha,beta-unsaturated nitriles to a pincer-based Ru-H complex affords structurally characterized kappa-N-coordinated keteniminates by selective 1,4-hydride transfer. When generated insitu under catalytic hydrogenation conditions, electrophilic addition to the keteniminate was achieved using anhydrides to provide alpha-cyanoacetates in high yields. This work represents a new application of hydrogen transfer catalysis using alpha,beta-unsaturated nitriles for reductive C-C coupling reactions.
